Detection of the Stuck-at-0 faults (SA0) on 4x16 decoder
                    Stuck at fault are of how many types
                  
                  
                  
                    SA0 fault detection model is used to 
                  
                  
                  
                    IC chip used for implementation of 3x8 line-decoder
                  
                  
                  
                    The 4x16 line-decoder implemented using two 3x8 line-decoders has enable as
                  
                  
                  
                    By considering Stuck-at-0 fault (line always passes signal 0) at different locations, all the SA0 fault cases can be identified
